Chemical stratigraphy has been playing an increasingly important part in solving stratigraphical problems.Nevertheless,its inter-discipline characteristics such as multi-step, intricate technology and high cost present critical requirements to its researchers for their comprehensive qualifications such as structure of knowledge.Deficiency of any step would bring defects or mistakes to the test result and study reliability.These problems have already been exposed one by one in chemical stratigraphy in the past twenty years.Hence the guaranteeing of original characteristics of testing samples constitutes a most important problem. The research resources could be focused to the proper targets in the process of sampling in field work and the preparation of testing samples in indoor study. With the help of cathode luminescence,the disturbance of diagenesis could be excluded and eliminated eventually.How to verify the systematic errors of testing instruments and how to make the most of these testing data are also the crucial problems which should be solved.Owing to the characteristics of carbonatite,debris and fossil shells,there are still some weak points that should be strengthened in chemical stratigraphy studies.
